brand new carmanah 47357 compact solar engine, 10w gen. this is used to power led street warning lights and beacons. has the ems unit ( controls everything ) inside the box and a place for the battery. this is for the solar panel and the box it's mounted on with the ems control inside only - there are no lights of any kind with this and we don not have them. Good start on a system or great repair parts for one that is not working or has been damaged! if nothing more a great unit to use as a swap out parts so you don't have to hang off a ladder beside a busy road to try to figure out what's wrong with it!
